MACHINE FOR MOLDING AND PRESSING BUILDING-BLOCKS.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed February 21, 1906. Serial No. 302,168.

To all whom it may concern:

Be it known that I, J ULIUs J AEGER, a citizen of the United States, and a resident of Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Machines for Molding and Pressing Building-Blocks, of which the following is a specification.

This invention relates to improvements in machines for molding and pressing buildingblocks of cement mixture, clay, or other compositions.

The object of my invention is to provide a new and improved machine of this kind which is simple in construction, and permits of making a number of blocks at the same time and in such a manner that the faces of the blocks are fully exposed for curing and are finished in a neat and perfect manner.

A further obj eot is to provide a machine in which the outer face of the block can be made of finer material than the balance of the block and thoroughly incorporated and' united with the coarser material forming the balance of the block, and a further object is to provide means for making blocks of different sizes and shapes.

In the accompanying drawings, in which like letters of reference indicate like parts in all the figures, Figure 1 is a vertical transverse sectional view through one end part of my improved machine for making buildingblocks. Fig. 2 is a similar sectional view at the other end. Fig. 3 is a plan view, parts being broken away. Fig. 4 is a vertical longitudinal sectional view of one end part of the machine on the line 4 4 of Fig; 2. Fig. 5 is a detail sectional plan view showing one end of the mold-box. Fig. 6 is an enlarged detail transverse sectional view through the mold-box reversed. Fig. 7 is a plan view of the bottom of the mold-box, parts being broken away and others shown in section. Fig. 8 is a side view of the mold-box closed, parts being broken away. Fig-9 is a plan view of a modified form of the baseplate.

The machine is constructed with two end standards A, united by a series of longitudinal horizontal rods A. Each end frame of the machine is provided with a horizontal bracket-arm B, on which supports B are held vertically adjustable by bolts B passing through longitudinal slots B in said supports. To the tops of the frames A at the rear an open frame C is hinged, on which a hopper C is formed, whioh'frame and hopper can be swung down into horizontal position, as shown in dotted linesin Fig. 1, or can be swung back out of the way, as shown in full lines in Figs. 1 and 2. A mold-box is formed and held between two side arms D, one at each end of the machine, which side arms are secured at their front ends to a rotatable shaft D, mounted in the upper parts of the frames A at the front thereof, so that by turning the shaft D the mold-box can be swung from the position shown in Fig. 2 through an arc of one hundred and eighty degrees into the position shown in Fig. 6 above the brackets B, said mold-box being thereby completely reversed while moving from the position shown in Fig. 2 to the position shown in Fig. 6. The mold-box has a base-frame formed of two longitudinal channel-bars E, the ends of which are secured to the two side arms D, and to the outer members of these channel-bars the mold-box sides are hinged by strap-hinges E, which sides are formed of two angle-bars E between which a longitudinal slot E is formed. Through the slots E screw-bolts F are passed, the threaded inner ends of which are screwed into suitable threaded holes in vertical plates F, which form the interior side walls of the mold-box. Said plates F may extend the entire length of the mold-box if a single block is to be formed at each operation or may be composed of as many vertical plates F as blocks are to be made at one time. For example, if fifteen blocks are to be made at one time, then fifteen vertical plates F are held by the screws F against the free edges of the flanges of the angle-bars E of each side, the side edges of these plates F being held apart a short distancesay about oneeighth of aninch, more or less for a purpose that will appear later on. The base-plates G of the mold-box rest upon the free edges of the flanges of the bars E, and each base plate or section thereof is held in place by two screw-bolts G passed through longitudi-' nal slots E in the bottom of the channel-bars E and having their upper threaded ends screwed into threaded holes in those parts of the plates G resting on the flanges of the channel-bars E. There are as many plates G in the bottom of the mold-box as blocks are to be made, and for each pair ofopposite side plates F there is one bottom plate G, and a space is left between the adjacent edges of each two bottom plates G of the same width as the space between the vertical plates F.

On the innerside of each end frame A two vertical rods H are mounted in brackets on the frame, and on said rods two sleeves H are mounted to slide vertically, which sleeves are united by a top plate H and a bottom plate H Two angle-bars J unite the top plates H at the front and. rear of the machine in such a manner that these angle-bars can pass within the space bounded by the inner flanges of the channel-bars E-that is to say, the channelbars J can pass up into the space bounded by the channel-bars E. Each anglebar J has a longitudinal slot J in its bottom flange, and the angle-bars are secured on the plates H by screw-bolts passing through slots J in the plates H, so as to permit of adjusting the bars J toward and from each other. A series of partition-plates K of such thicknesssay aboutone-eighth of an inch, more or lessthat they can pass through the slots between the vertical plates F and the horizontal plates G of the mold-box are secured at their lower ends to angle-bars K, which in turn are adjustably secured by bolts K passing through the slots J in the bottom flanges of the angle-bar s J, so that these partitionplates K can readilybe adjusted onthe anglebars J and so that these partition-plates K will be in exact alinement with. the slots between the vertical plates F and horizontal plates G.

A cam-disk L is located between the top and bottom plates H and H" on each side of the machine, and these cams are secured on a rotatable shaft L, extending horizontally and lengthwise of the machine, so that when this shaft L is rotated in one direction or the other the cams L will lower or raise the united plates H and H and thereby lower or raise the partitions K. When the plates H H are lowered, the partition-plates K are withdrawn entirely beneath the upper surface of the bottom plates G of the mold-box, and when the plates H H are raised to the full limit the partitions K extend to the top of the sides of the moldbox. The end plates M of the mold-box rest upon the upper surface of the extreme end plates G and can move horizontally and on edge on the same, and

these end plates are provided with triangular or like ridges h which can pass into corre sponding recesses h 2 in the ends of the anglebars E forming the front and rear sides of the mold-box, as shown in Fig. 3. Each end plate M is provided with an internallythreaded hub N, in which a screw 1V is mounted to turn, which screw is formed on the inner end. of a short shaft N, mounted to turn in one of the pivoted side bars D, and to the outer end. of said shaft N a wheel O fol turning said. shaft is secured, as shown in Fig. 4. At the top edge each end plate M is provided with a hook-lug m, extending toward the interior of the mold-box. A shaft Q, mounted longitudinally and horizontally in the frames A, is provided with a crank-handle Q at each end outside of the frames A, and at one end this shaft Q carries a small cog-wheel Q which engages a larger cog-wheel Q fixed on one end of the shaft D. The cog-wheel Q also engages a cog-wheel Q which in turn engages a cog-wheel Q secured on the shaft L, previously mentioned. The cog-wheel Q is mutilated and is devoid of teeth at the parts b and (Z, and at d an arm R, secured to the side of the cog-wheel Q projects beyond the rim of the same and can be engaged by a pin R, projecting laterally from the cog-wheel Q The cog-wheel is devoid of teeth at the part 9 and at g is provided with an arm S, projecting beyond the rim of the cog-wheel and adapted to be engaged bya pin T, proj ecting from the side of the cog-wheel Q The operation is as follows: When a series of blocks are to be made, the partitions K are all in raised positions-as shown, for example, in Fig. 4-and are held in this raised position by the cams L. The mold-box is in the position shown in Fig. 2, and the hopper is swung over the mold-box, as shown in dotted lines in Fig. 1. The material for making the blocks-for example, a cement mixtureis fed into the hopper and passes from the same into the molds formed between the partitions K, and the material is carefully tamped in these molds. When a block with an extra surface finish is to be madefor example, a block or brick to be used as a front brick- -finer material or colored material is placed in the bottom of each mold to a thickness of about one-half of an inch, more or less, and is tamped, and then the coarser material is placed upon the finer material in the bottom of each mold and also carefully tamped. The hopper is then swung back into position shown in Figs. 1. and 2 and the material scraped off the top of the mold-box flush with the upper edges of the partitions K. A plate WV, made of cast metal or of slate of such di mensions as to fit over the mold-box, is placed upon the upper edges of the partitions K and between the end plates M, as shown in Fig. 4, and then the wheels O at the two ends of the machine are so turnedv as to press the end walls M firmly against the ends of the. sides of the mold-box, these end walls having been temporarily Withdrawn to permit inserting the plate W. The ridges M pass into the recesses M whereby the mold is securely locked, and at the same time the hook-lugs m pass over the upper surface of the plate WV at the ends thereof, thus securely locking the plate in place on the top of the mold-box. By turning the crank-shaft Q in the direction of its arrow, Fig. 1, the cog-wheel Q is turned in the direction of this arrow without, however, affecting the cog-wheel Q, as the blank space I] in the rim of the same is now at the highest point of the cog-wheel By rotating the cog-wheel in the direction of its arrow TTO the cog-wheel Q is turned in the direction of its arrow and the cog-wheel Q is turned in the direction of its arrow until the teeth of the wheel Q arrive at the blank space 9 of the cog-wheel Q By that time the shaft L has been turned to such an extent that the cams L have forced down the plates H H and the angle-irons J and the partitions K on these angle-irons, whereby these partitions K are withdrawn through the slots between the bottom plates G until these partitions are entirely withdrawn from that part of the moldboX above the bottom plates G. By this time the pin R on the wheel Q has arrived at the arm R and engaging the same pushes the cogwheel in the direction of its arrow until the teeth at the left of the recessed part d of the cog-wheel Q engage the teeth of the cog-wheel Q whereby the cog-wheel Q and its shaft D are turned in the direction of the arrow of the cog-wheel Q and whereby the arms D are swung in the direction from right to leftthat is, from the position shown in full lines in Fig. 2 into the position shown in Fig. 6--whereby the mold-box is reversed and the upper surface of the plate W (now the under surface) rests upon the upper edges of the supports B of the brackets B. The hand-wheels O are now turned so as to withdraw the end partitions M, whereby the side walls of the mold-box are released and can swing outward slightly, as shown in Fig. 6, and at the same time the plate IN is released from the end plates M. The blocks or bricks made now rest entirely upon the plate IV. The crank-shaft is now turned in the inverse direction whereby the cog-wheel Q is turned in the inverse direction and the arms D are turned back one hundred and eighty degrees into their original position, the mutilated part (I of the cog-wheel Q being brought back into the position shown in Fig. 1. At the same time the cog-wheel Q is turned in the inverse direction of its arrow, but without any effect, as the recessed part 9 of the cogwheel Q is now. at the rim of the cog-wheel Q; but by this time the pin T of the cogwheel Q has arrived at the arm S and has turned. the cog-wheel. Q in the inverse direction of its arrow, so that the teeth of the cogwheel are again engaged with the teeth of the cog-wheel Q and the shaft L is turned in the inverse direction of its arrow, whereby the cams L are so turned as to force the parti tions K up through the slots in the bottom of the mold and into the position shown in Fig. 4, when blocks can again be made in the manner described.

The mold-box can be adjusted in width to make bricks of any desired length, and the base and side plates can be adjusted for making blocks of various sizes. For example, the base-plates G may be replaced by a single plate G having a series of openings G for cores of various sizes. inclosing the gearing.
